Reactivity of chlorodimethylsilyl η5 cyclopentadienyltrichlorotitanium with nitrogen based donors X ray molecular structure of [Ti{η5 C5H4SiMe2[η1 N(2,6 Me2C6H3)]}Cl2]

Then, the reaction was diluted with 10 mL of AcOEt and washed with a 0.1 M solution of NaHCO 3 in brine (3x10 mL), and water until the pH becomes neutral. The organic phase was

The resulting solution was transferred to a filter unit (Amicon Ultracentrifugal 100K) and filled with 3.0 mL of water. This centrifugation process was repeated 2 times to

After filtration of the drying agent, the solvent was removed under reduced pressure, and the residue purified by column chromatography on silica gel (eluent: heptane/ethyl

The organic phase was washed with saturated aqueous solutions of NaHCO 3 and NaCl, dried over Na 2 SO 4 , and the solvent was removed under reduced pressure to obtain the

f The culture was transferred to minimal medium with For the estimation of molecular weight by gel cellulose as the sole carbon source (1000 mL) and after

The turbid yellow supernatant was removed and the black solid was washed twice with 9 mL of acetone and twice with 9 mL of THF, isolating it by means of centrifugation for 5 min at

The reaction mixture was diluted with AcOEt (50 mL) and washed with water (3 × 50 mL), dried (Na 2 SO 4 ) and concentrated in vacuo and the crude mixture was purificated by

The organic layer was separated, dried with MgSO 4 , the solvent evaporated to dryness and the residue purified by column chromatography (SiO 2 : DCM). The solvent
